1 Clama (CL 251-114).

'Ijhissinvention relates to a valve and itis one object of the inventionrtovprovide a valveadapt;- el: to be installed ina pipe line; throughl which gasyoil; or water flows and serve to preventQw oigrthe uid from theY pipev linein case thepipe line becomes broken at a point between the valve and the place to which the uid is being delivered.

Another object of the invention is to provide a valve of such construction that it may be set for any pre-determined pressure and thus allow fluid under the pre-determined pressure to ow freely through the valve, increased pressure caused when a break occurs serving to close the valve and shut o flow of the fluid through the same. v 1

vAnother object of the invention is to provide a valve consisting of a plurality of parts which may be easily and quickly assembled to form the complete valve. f

Another object of the invention is to provide a valve of this character of such construction that uid entering the same will be directed as a jet towards a concaved surface of a valve disc and thus centered relative to the valve disc so that the disc will be quickly moved to a closed position when subjected to pressure greater than the valve is set for. e

The invention is illustrated in the accompanying drawings wherein the figure shows the improved valve in longitudinal section.

This improved valve has a hollow body or casing I consisting of heads 2 and 3 and a spacer 4, the head 3 being formed with an annular skirt 5 and the spacer 4 being disposed between this skirt and the head Zand bolts 6 being passed through aligned openings formed through the heads and the spacer and having their nuts l tightened to hold the parts in tight fitting engagement'with each other. A coupling 8 `extends outwardly from the head 3 for engagement with a supply pipe and in alignment with this cou-y pling there has been provided an inwardly extending tapered nozzle 9 so that the uid from Y the supply pipe will be discharged as a jet axially of the valve casing.

The head 2 is formed integral with an outlet tube or neck I0 which has its outer end externally threaded, as shown at Il, vfor connection withv a pipe through which the gas or other uid is to pass to a place of use. The inner end portion I2 of the tube I0 is tapered so that the disc I3 which is fitted into the'opening I4 of head 2 Awill be firmly seated and prevented from moving outwardly beyond the position shown in the and from these seats lead ports I6 through which the fluid flowsfrom the casing into the outlet pipe or tube I0 and it will be understood that any desired number of seats I5 and ports I6 may be provided consistent with the size of the disc. A second disc I1 is screwed into the tube I0 for longitudinal adjustment therein and through this disc are formed a number of ports I8 through which the fluid passes. Center openings I9 and' 20 are formed through discs I3 and I'I to slidably receive the stem 2| of a valve head or disc 22 disposed within the casing I and it should be noted that the opening I!! and the portion 2| of the stem 2l passing through it are square to prevent the stem from turning in the opening I 9. For the remainder of its length the stem is of reduced diameter and circular in cross section and its outer end is threaded and carries nuts 23. A springrZ surrounds the stem 2| between the disc and the shoulder 25 at the end of the squared portion of the stem and urges the valve head 22 away from the disc I3 to its open position. By adjusting the position of the disc I1 in the tube IIJ, the pressure required to move the valve head towards the disc I3 to a closed position in which its hemispherical bosses 26 enter the seats I5 and close the valve may be controlled. The surface 2'! of the valve head 22 confronting the nozzle 9 is of concaved cupshaped formation and when the jet of fluid strikes this surface, it will be centered relative to the head 22 and the stem ZI and its force will tend to shift the valve head towards av closed position. YBy setting the disc I1 to tension the spring 24 for resisting a pre-determined pressure, the valve head will be held open and the the fluid may flow through the ports I6 into pipe or tube I0 and through the ports I8 into a distributing pipe line connected with the threaded line or for some other reason the fluid flows with increased pressure through the casing I its force will shift the valve head towards disc I3 and the bosses ,2B will enter the seats I 5 and shut off ow of fluid through the tube or neck I0. As soon as the break in the distributing line is fixed pressure will equalize itself in the casing and the lneck or tube and the valve head 22 will be re- Since elements forming the casing are held together by the bolts 6, the casing may be easily taken apart for cleaning the valve or making replacement of parts when necessary.

What is claimed is:

In a valve device, a casing having a front head and a rear head, a spacer separating the heads, the rear head being formed with an annular skirt and bolts passing through the spacer and the front and rear heads and the annular skirt of Said rear head to retain said heads and said spacer in ixed relation to each other, a coupling extending outwardly from the rear head for attachment to a supply pipe, the inner end of the coupling having a tapered nozzle to cause uid to be discharged axially of the casing, an outlet neck formed integrally with the front head and having a tapered portion, a first disc tted in the tapered portion at the connection with the front head of the neck, said rst disk having cup-- shaped recesses and ports therethrough communicating with the recesses, a second disc screwed into the. neck for longitudinal adjustment and having ports therein, a valve stem passing through the two discs, the portion of the rod passing through the first disc having means to prevent rotation of the rod, a valve head attached to the stem and a concave surface to receive fluid from the nozzle, said valve head having semi-spherical projections adapted to rest in the recesses in the first disc, and spring means to normally hold the valve head away from the rst disc.
